Hello everyone! Just a heads up News Post that due to the upcoming removal of free access to Twitter's Application Programming Interface (API) on February 9th, it is recommended you switch the primary alias you use for World of Lingua, as the stuff we use to manage account linking on Twitter might break. You can do this from the Aliases Page in the Setting Tab. Keep in mind that you may have to re-link a different account if the API changes make account linking non-functional, but otherwise, nothing will happen to your account. We're sorry to see Twitter make this change, but we'll adapt to it.
